Looking for O-ring size

[brian_null]

I'm looking for the standard size of the o-ring that fits in the female fitting on a Foster connection. Any idea as to buna rating?

o-ring is a 010

Thanks, Haji

-010 is correct for most, I would use a 90 duro.

There are some that apparently take a -009

 

[Humdinger]

All of mine take 009. 90 Durometer lasts longer.

Thanks, guys. As cheap as they are, I'll just buy a bag of both.
